Abstract:
Flexure at the tooth cervix might render the restored Class V lesions to degradation. In this clinical trial a total of 76 carious cervical lesions in both arch were restored using Prime & Bond NT and Clearfil SE Bond adhesives, along with Clearfil APX composite resin. Retention of restoration, marginal discoloration and postoperative sensitivity were evaluated during a one year period. The overall clinical success rate was 89.5%, while no significant difference (p > 0.05) was found regarding postoperative sensitivity or marginal discoloration between two adhesives. Retention loss was associated only with self-etch adhesives. No association was found between clinical success and dental arch location.
